Researchers at Caltech, Harvard and MIT have been working with colleagues in Europe to come up with a method of boosting wireless network performance. What they've created is a network that is 10 ...

When more and more video joins the network, and it is prioritized above data traffic, the data will begin to suffer from more congestion loss. That affects all productivity apps, and thus productivity ...

Before continuing on to cover which of the various technologies – those that are part of the Next-generation Enterprise WAN (NEW) architecture as well as others – addresses packet loss and how, I ...

Interface packet loss provides indications of link problems that shouldn’t go ignored. But then you have to decide on an alerting threshold that indicates a problem without creating too many false ...

Last time, we began our discussion of what can be done to address the impact of packet loss on application performance over the WAN. We listed six different possibilities, and went through how one of ...

Stream Control Transmission Protocol (SCTP) is a new transport layer protocol, proposed by IETF in RFC 4960. In this paper, the authors have done a simulation-based comparison of important Quality of ...

When I run Wireshark on my machine, I notice lots of duplicate ACKs and retransmits. Sometimes, the loss will be on initially setting up TCP connections, and others it's during the connection. I think ...

The discarding of data packets in a network when a device (switch, router, etc.) is overloaded and cannot accept any incoming data at a given moment. High-level transport protocols such as TCP/IP ...

Have you ever performed surgery on data packets? There are times when that may be the best way to troubleshoot and optimize your network. This edition of the Packet Professor will get you started in ...
